The main ingredient in this fruity, refreshing, and extremely brunch-appropriate cocktail is a spirit called Dimmi Liquore di Milano. Floral with a big hit of stonefruit, Dimmi is a blend of neutral grain spirit (basically a wheat vodka) and Nebbiolo grappa. It's infused with a variety of botanicals including wormwood, vanilla and rhubarb. At 35% this is a versatile spirit to play around with in low alcohol cocktails, but it's also pleasant served chilled on its own.
1.5 oz Dimmi Liquore di Milano .5 oz hibiscus liqueur (I use Fruitlab)
1.5 oz fresh grapefruit juice 1.5-2 oz Cava or Prosecco Shake everything but the sparkling wine and strain into a rocks glass. Top with Cava/Prosecco, about 1.5oz or so. Garnish with a cherry.
